erly formulated and carefully manufactured dental alloy, one needs a good investment, the proper equipment, and well-defined, easily usable tech-nique. The high level of accuracy of the fit that dental castings of today have reached is the result of im-provements made in all of these areas — namely, alloy, investment, equipment, and casting. Dental alloys are diverse in composition, ranging from nearly pure gold and traditional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1).The types of dental alloys available to the dental practitioner have increased dramatically since the start of the 1980s in response to changes in the market price of gold and palladium. Advances in Dental Research In recent questionnaire surveys about side-effects, the incidence was estimated to be Dental casting alloys may contain nickel, chromium, cobalt, or palladium. The inherent strength of dental casting alloys allows them to restore large damaged or missing areas and be used in ways that protect the tooth from future fracture injury. Such restorations include onlays and crowns
